Today (June 5th, 2013), we are celebrating the COJ's 3 Year Anniversary! In these three years, we have seen our community grow from the ground up, we have worked hard to keep fixing bugs, incorporating new functionality, taking your suggestions into account and specially, keeping the problemset fresh and the contests alive!

We would very much appreciate hearing from you, our dear users. Tell us what you think of our system (both positive or negative), how has your experience been on these three years, and what are your expectations on the years to come.
